摘要
目的探讨应用Sky骨扩张器系统行椎体后凸成形术治疗骨质疏松性压缩骨折的早期临床疗效。方法12例骨质疏松症17个压缩性骨折椎体，采用Sky骨扩张器行单侧经椎弓根椎体扩张，扩张高度为14mm，注入医用骨水泥。观察围手术期并发症，测量压缩椎体和后凸畸形恢复程度。采用疼痛视觉模拟评分（visual analogue scale，VAS）随访患者胸腰背部疼痛恢复情况。结果每个椎体手术时间（52．4±28．7）min（23—90min），骨水泥注射量为（5．4±1．0）ml（3．5—7ml）。随访3～6个月，平均4．5月，术前VAS评分为（7．6±1．8）分，术后1天为（2．8±1．1）分，术后3天为（2．6±1．2）分，末次随访时为（2．2±1．0）分。术前椎体前缘高度（13．8±5．3）mm（压缩49．1％±19．1％）、中线高度（9．9±4．6）mm（压缩39．8％±18．4％），术后椎体前缘高度（16．6±4．8）mm（压缩59．1％±17．2％）、中线高度（15．2±4．0）mm（压缩60．6％±16．9％），手术前后单椎体后凸Cobb角为22．3°±8．5°和12．5°±6．4°。1例少量骨水泥渗漏入椎间盘，未出现临床不适，未见其他并发症。结论采用Sky骨扩张器系统行经皮椎体后凸成形术治疗骨质疏松性压缩骨折安全、有效，其长期疗效尚有待于进一步观察。
Objective To investigate the early clinical efficacy of percutaneous kyphoplasty using the Sky Bone Expander system in the treatment of osteoporotic compression fractures. Methods Twelve cases of osteoporotic vertebral body compression fracture （17 vertebrae） underwent percutaneous kyphoplasty using the Sky Bone Expander system. During the operation the unipedicle technique was applied and the expansion height was 14 mm for bone cement injection. Surgical complications and the restoration of vertebral height and kyphosis angle were observed. The pain of thoracic and lumbar region on the back was evaluated with the visual analogue scale （VAS）. Results The operative time for each vertebra was 52.4 ± 28.7 rain （range, 23 -90 min）, with a volume of 5.4 ± 1.0 ml （range, 3.5-7 ml） of cement injected. A follow-up was made for 3 -6 months （mean, 4.5 months）. The VAS scores were 7.6 ± 1.8 points preoperatively, 2.8 ± 1.1 points at day 1, 2.6 ± 1.2 points at day 3, and 2.2 ± 1.0 points at last follow-up. Preoperatively, the anterior vertebral height was 13.8 ± 5.3 mm （ compression by 49.1% ± 19.1% ） and the midline vertebral height was 9.9 ±4.6 mm （compression by 39.8% ± 18.4% ） , while postoperative anterior and midline vertebral height were 16.6 ± 4.8 mm （compression by 59.1% ± 17.2% ） and 15.2 ± 4.0 mm （compression by 60.6% ± 16.9% ） , respectively. The kyphotic angle was decreased from 22.3° ± 8.5° preoperatively to 12.5° ± 6.4° postoperatively. Intervertebral disc leakage of bone cement was observed in 1 ease with no symptoms. There were no other surgical complications. Conclusions Kyphoplasty using the Sky Bone Expander system is an effective and safe treatment for osteoprotic vertebral compression fractures. The long-term outcomes are subject to further observations.
